A needle is inserted into the right somatosensorynucleus of the thalamusin the central nervous system and thearea is injected with GABA.
1. Through what structure does a primary sensory neuronfrom the hand enter the central nervous system?
2. Where does the first synapse forthis somatosensory pathway occur?
3. Describe the type(s) of sensoryinformation carried by this pathway.
4. Name and describe two differentclasses of primary sensory receptors that are associated with thispathway.
5. Discuss the common features that all primary sensoryreceptors possess.
6. If an adrenergic substance had been injected insteadof GABA, how would this have altered neural transmission?Explain.
